It was selected for the JICA 2017 project formulation survey.

High storage capacity with a porosity of over 95%! Excellent seismic strength and easy to assemble.

"Pradam-kun" is a rainwater storage tank that has a significant retention effect due to over 95% void space (in cases where the facility height is 1.2m or more), reducing excavation and residual soil volume, thereby lowering total costs. The accumulated sand and other materials can be easily removed using an inflow device, making maintenance simple, and it can be installed under parking lots due to its excellent compressive strength. 【Features】 ◆ Achieves high water retention with over 95% void ratio! (in cases where the facility height is 1.2m or more) ◆ Excellent seismic strength, usable even under parking lots! ◆ Main components are one part, and assembly is completed by simply connecting dedicated joints! ◆ Usable for both storage and infiltration facilities! *For more details about the product, please download the catalog or contact us.

Outstanding water treatment capability significantly reduces construction area! No piping work required, shortening the construction period! Equipped with maintenance features!

In accordance with the new technical guidelines of the Public Interest Incorporated Association for Rainwater Retention and Infiltration Technology, we have launched a model-changed new standard "New Trench-kun II" (product dimensions remain unchanged). Improvements have been made compared to the conventional model as follows: - Compliance with the new technical guidelines of the Public Interest Incorporated Association for Rainwater Retention and Infiltration Technology - Improved connection pieces for easier assembly - Elimination of transport pipe ribs, allowing for internal inspection of the tank with a camera The plastic rainwater retention and infiltration facility, infiltration trench "New Trench-kun II," significantly reduces construction area with its excellent void ratio. No piping work is required, assembly is extremely simple with one-touch connections, and construction time is shortened. It is compatible with T-25 and can be installed under parking lots. The unique internal maintenance function of New Trench-kun II makes maintenance very easy. Due to these features, a cost reduction of 0-40% compared to conventional crushed stone trenches is possible (this varies by administration, so please contact us for details). *New Trench-kun II is a previously registered product in the Ministry of Land, Infrastructure, Transport and Tourism's new technology information provision system 'NETIS' (old registration number KT-130092-A).

Usually conserve water; in emergencies, secure precious water! With a rainwater storage tank at seismic resistance level 2, prepare for another contingency in case of emergencies!

The Plus Pool is an underground buried plastic rainwater storage tank. Being underground, it doesn't take up space and can be installed in various locations such as residential gardens and small-scale community disaster prevention centers! During normal times, it allows for easy water conservation and an environmentally friendly lifestyle! It can be used for outdoor washing tasks such as watering the garden and washing cars. In emergencies like disasters, it secures valuable domestic water for flushing toilets and laundry! It ensures seismic strength level 2 (equivalent to the Great Hanshin-Awaji Earthquake), allowing for safe use even in emergencies. It has a large capacity that can support a family of four for one month! (Calculated based on one person needing 40 liters per day) It can also be used during power outages with the installation of a hand pump. In February 2021, we renewed the catalog by adding construction example photos!

Starting from October 2025, Panasonic's indoor units for office and store air conditioners will be renewed! In this renewal, all models will come standard with "100 times nanoe X." This not only enhances comfort with commercial air conditioning but also contributes to improving air quality. Additionally, improvements in installation efficiency to enhance on-site work productivity and a strengthened lineup to accommodate diverse spaces have been implemented. The new indoor units are equipped with high concentrations of nanoe X as standard! They demonstrate a high effectiveness in purifying indoor air during air conditioner operation, providing a safer and more comfortable environment for office and store users and employees. Furthermore, the center of the suction inlet and the center of the hanging bolt have been unified. This allows for the combined use of canvas ducts and panels, improving installation efficiency. If you have any questions or would like a quote, please feel free to contact us. We will fully support you in replacing your commercial air conditioning!

Kort Valuta Inc. (Head Office: Shibuya, Tokyo; CEO: Hideki Shibata) is pleased to announce that we will hold our next recruitment event, “Kort Valuta Night,” on November 26, 2025.

Our efforts to balance energy conservation and comfort through "Akarina," as well as the initiatives we have undertaken together with the companies that have adopted it, have been recognized. We sincerely thank everyone who has supported and adopted Akarina for their invaluable assistance.

We are pleased to announce the development of the vehicle passage time prediction system "MS-VPP," which measures the speed of vehicles approaching construction sites using microwave sensors and informs the predicted passage time through signage and tablets. This system will be available to construction contractors starting in November 2025. ■Product Overview - "MS-VPP" detects vehicles approaching construction sites and measures their speed using microwave sensors, displaying the vehicle speed and the predicted passage time at specified locations on signage and tablets. It can also measure and display data for vehicles passing continuously. - The data control panel connected to the microwave sensor transmits the vehicle speed data and calculated passage prediction time via LTE. By utilizing microwave sensors, it enables accurate detection and speed measurement of vehicles even at night or in bad weather, and since data processing occurs on the receiving side without going through the cloud, information can be displayed without any time lag. - As a result, drivers of construction vehicles exiting from construction entrances and workers directing traffic can understand "how many seconds until a vehicle passes near the site entrance," thereby implementing safety measures in areas with poor visibility.
